Popis: Acid catalyzed double rearrangement of the ethyl 6-oxa-2,2, 4,4-tetramethyl-1-azabicyclo[3,1,0]hexane-3-carboxylate leading to ethyl 1,2,4,5-tetramethyl-pyrrole-3-carboxylate is proposed on the basis of identification of the intermediate ethyl 5-hydroxy-1,2,4,4-tetramethylpyrroline-3-carboxylate.
